One of the Best things about Biogas is that we can obtain it with no Combustion, Which Means that the Biogas Production Process Has a Minimal Impact on The Environment and Doesn’t Generate High amounts of Greenhouse Gas Emissions Like Fossil Fuel, etc. Biogas is a mixture of gases made from raw materials such as agricultural waste, manure, municipal trash, plant material, sewage, green waste, and food waste. The main gases in biogas are methane, carbon dioxide, and hydrogen sulphide. It is a renewable source of energy.
